There are currently no standards for characterization and calibration of the cameras used on unmanned aerial systems (UAS's). Without such standards, the color information in the images captured with these devices is not meaningful. By providing standard color calibration targets, code, and procedures, users will be empowered with the ability to obtain color images that can provide information valuable for agriculture, infrastructure, water quality, even cultural heritage applications. The objective of this project is to develop the test targets and methodology for color calibrating unmanned aerial vehicle cameras. We are working to develop application-specific color targets, the necessary code, and a qualitative procedure for conducting UAS camera calibration. To generate the color targets, we will be following approaches used in the development of ISO 17321-1: Graphic technology and photography — Colour characterisation of digital still cameras (DSCs) — Part 1: Stimuli, metrology and test procedures as well as research evaluating application-specific camera targets. This report reviews why a new industry standard is needed and the questions that must be addressed in developing a new standard.
